Reinforced concrete designs (Solution working stresses method)

Required information For the concrete beam shown, the modulus of elasticity is 25 GPa for the concrete and 200 GPa for the steel. Take b=218 mm and d = 450 mm. Use an allowable stress of 12.5 MPa for the concrete and 140 MPa for the steel. NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. Using the area of steel calculated in part a, determine the largest allowable bending moment. The largest allowable bending moment is 96.06 kN-m.

A rectangular plate is subjected to uniform biaxial stress with x = 90 MPa (tension), oy = -20 MPa (compression), and ₂ = 0. The plate has original dimensions 400 X 800 X 200 mm (x X y X z) and is made of steel with E = 200 GPa and v = 0.3. What are the strains Ex, Ey, and Ez?

You must have to draw FBD

USE NSCP 2010 A reinforced rectangular concrete beam has a width of 250 mm and aneffective depth of 360 mm. It is reinforced for tension only at the bottomwith a total tension steel area of 600 mm². fc’ = 40 MPa, fy = 400 MPa. a. Determine the tension reinforcement index for this beam.b. Determine the distance of the neutral axis below the compressionsurface. c. Determine the ultimate flexural strength of the beam.
